New 3-carbalkoxyamino-5-(alpha-aminopropionyl)-5H-dibenz[b,f]azepines of formula I and their pharmaceutically acceptable salts were found to be suitable actives for the treatment of cardiac arrhythmia. Previously unknown 3-carbalkoxyamino-5-(alpha-halogenpropionyl)-5H-dibenz[b,f]azepines are obtained from 3-carbalkoxyamino-5H-dibenz[b,f]azepines by reaction with alpha-halogenpropionyl halides. Through their reaction with ammonia, primary amines or secondary amines, the new 3-carbalkoxyamino-5-(alpha-aminopropionyl)-5H-dibenz[b,f]azepines are obtained, which can be optionally converted into their pharmaceutically acceptable acid addition salts.
公式I的新型3-羧酸酯氨基-5-(α-氨基丙酰基)-5H-二苯[b,f]氮杂环及其药学上可接受的盐被发现适用于治疗心律失常。3-羧酸酯氨基-5H-二苯[b,f]氮杂环通过与α-卤代丙酰卤反应,获得了以前未知的3-羧酸酯氨基-5-(α-卤代丙酰基)-5H-二苯[b,f]氮杂环。通过它们与氨、一级胺或二级胺的反应,可以获得新的3-羧酸酯氨基-5-(α-氨基丙酰基)-5H-二苯[b,f]氮杂环,这些化合物可以选择性地转化为药学上可接受的酸盐。
